Clutch/CSC failure approaching
 

Hello all, I have a Nissan 370Z and have had some weird things going on. Nothing is broken as of yet. Sometimes when driving the Z hard through shifts and yesterday when I did a donut my clutch pedal lost pressure. It wasn't complete loss of pressure the clutch would still work but the pedal travel was much further. After about a hour it seemed to stiffen up a little bit again. I've also experienced one time a complete loss of pressure about a year ago, but pressure returned after about 2-3seconds. For those of you experienced with the CSC, does this sound like normal operation or sign of a failure approaching. I have had zero clutch work done to the car that I know of. (3rd owner, car was bought with 58k on odo)

The clutch hydraulic system has a high failure rate. It sure sounds like the CSC and/or CMC is going out. If you are on a tight budget, I'd flush the system (CMC to CSC) and see if that will buy you a little more time.

Is it possible your fluid is getting too hot? Maybe a switch to better fluid and some heat shielding on the lines is all you need. ZSpeed sells a SS line with DEI Heat shield on it, but you can get the shielding at the autoparts store as well and just insulate the OEM line.

Okay I'll do a fluid flush soon. Thank you both for the replys!

Flush the fluid, but go ahead and talk to Joe@Zspeed. A fluid change is a bandaid if the csc is really on the way out. Might as well know how much it's going to sting ahead of time.
